Method and apparatus for reconfiguring a material processing plant

A mobile material processing plant comprising:

• a chassis,
• a crusher, having an input, disposed on the chassis;
• a screen disposed on the chassis;
• a conveyor receiving material from said screen and elevating it to a position above the input to said crusher;
• a dual positionable chute disposed between said conveyor and said input to said crusher;
• said dual positionable chute is not configured with predetermined apertures therein to allow passage of material there through that is smaller than said predetermined apertures,
• wherein said material processing plant utilizes only gravity and hinging of said dual positionable chute to move material exiting said conveyor to the input of said crusher;
• and
• said dual positionable chute being configured, to pivot about an axis so that material falling from said position is directed in different directions depending upon a hydraulic pressure in an actuator which has a linear dimension which changes depending upon hydraulic pressure.

A method of redirecting material off a crushing plant with a chute in an open circuit position comprising the steps of:

• providing dual actuators coupled to the chute, wherein said chute does not include a vibrating screen with predetermined apertures therein to allow passage of material there through that is smaller than said predetermined apertures, and when said dual actuators are fully extended or until a first end of the chute rests against a hinge mechanism directing the chute away from a feeder hopper;
• allowing for material to be rejected from the plant cycle and safely removed;
• allowing for oversized rock material to exit a recirculating conveyor, and travel down the chute onto an off-plant location;
• and
• wherein only gravity and hinging of said chute are used to move material exiting said recirculating conveyor to said feeder hopper.
